FAQ
How do I test my microphone online?+
Click Start test, allow microphone access when your browser prompts, then speak. The level meter and waveform will react to your voice. Click Record to capture a sample and Play to hear yourself back.
Why is my microphone not working?+
The most common causes are (1) microphone access blocked in the browser — click the permissions icon in your address bar and allow the mic; (2) the wrong input device is selected in your OS settings; (3) the microphone has a hardware mute switch that's on; (4) another app (Zoom, OBS, Discord) is holding exclusive access. Try quitting other apps and refreshing this page.
Does this record my voice on your server?+
No. Everything runs in your browser. If you use the Record button, the audio blob is held in memory only and is discarded when you close the tab.
What browsers are supported?+
Any modern browser that supports the MediaDevices and Web Audio APIs — Chrome, Edge, Firefox, Safari, Brave, and Arc all work. On iOS Safari, playback of your recording requires a user tap.
